Current Permit Information and Guidance Documents (12-SW)
Change in Required Documentation
In recognition that the permit is beyond its five-year term, and in recognition that NPDES permits have a maximum duration of five years, the Department is discontinuing the acceptance of new registrations under permit 12-SW-A. Proposed new discharges of stormwater associated with industrial activity submitted will not be allowed to obtain general permit coverage until a new permit is issued.
In place of permit coverage under the expired permit, the Department has issued an Order to cover proposed new discharges of stormwater associated with industrial activity if an applicant meets the 12-SW-A eligibility criteria and declares intention to operate in accordance with the terms of the Consent Order and 12-SW-A. The applicant should submit a Declaration of Intent and complete the registration/certification process in accordance with the requirements otherwise set forth for registrations under permit 12-SW-A.
Note that existing registrations under the General Permit 12-SW-A continue to be covered under the existing administratively extended permit (per the
terms of the permit).

Once a draft of the new permit has been proposed to open the public
participation process, the Department will take comments prior to arriving at a
final permit.
